Computers are like air conditioners.
They stop working when you open Windows.

Looks like your BIOS doesn't want to give up the USB controller. Is
there any USB settings in the BIOS that you can change?

This is a BIOS screwage. What was the last kernel that worked?

It's never worked. I've actually given up - it was during some testing of some
Samsung early prototype set-top-computers ... They hang if I try to disable
USB legacy support in BIOS. They hang if I try to reboot, and they hang if I
use red post-it notes on them
thanks anyway
